First report and damage description of Calodesma collaris (Drury, 1782) (Lepidoptera: Erebidae) caterpillars on Aechmea winkleri Reitz, 1975 (Bromeliaceae).

We report for the first time the occurrence of Calodesma collaris (Drury, 1782) (Lepidoptera: Erebidae) caterpillars on Aechmea winkleri Reitz, 1975 (Bromeliaceae) and describe the damage it causes on these plants. The consumption of leaf tissue, accumulation of excrements and inhibition of inflorescence emission caused by larvae of C. collariscan result in plants of A. winkleri that are not suitable for ornamental or landscaping purposes

Department of Dermatovenerology, State University of Medicine and Pharmacy "Nicolae Testemitanu", Chișinău, Republic of Moldova, Congresul consacrat aniversării a 75-a de la fondarea Universității de Stat de Medicină și Farmacie „Nicolae Testemițanu” din Republica Moldova, Ziua internațională a științei pentru pace și dezvoltareIntroduction: Cutaneous tuberculosis is a group of polymorphous and varied manifestations of the skin and mucous membranes, produced by infection with some species of Mycobacterium tuberculosis complex. The specific primary lesion is the lupoma, sometimes evolving into mutilating forms. Purpose: Lupus vulgaris particularities reported in two clinical cases. Material and methods: A 68-year-old female, presented for multiple infiltrative, prominent erythematous plaques and placards with various diameter, well contoured by a violaceus halo, with irregular contour on the trunk. A 6-year-old boy presented for brownish-red, soft papules with smooth surface on the face and trunk. The lesions appeared 3 years ago; and 6 months ago after a minor trauma injury, the lesions have spread. Results: Chest X-ray didn’t reveal any abnormalities. During dermascopy the sign of “apple jelly” was found positive. Histopathological exam found caseous necrosis, tuberculoid granulomas composed of epithelioid cells and Langhans giant cells, surrounded by mononuclear and a dense lymphocyte infiltrate localized in the dermis. Mantoux probe was 17 mm in diameter. Clinical examination sustained by the histopathological exam and Mantoux probe inferred the diagnosis of lupus vulgaris (tuberculosis). Conclusions: The particularities of the presented cases with distinct clinical signs, the histopathological presence of granulomatous inflammation with specific cellular appearance, the hyperergic Mantoux test and the lack of characteristic pulmonary changes represent a casuistic interest of lupus vulgaris

First record of Dysmicoccus boninsis Kuwana, 1909 (Hemiptera: Pseudococcidae) on sugarcane in the state of Rio Grande do Sul.

Among the sap-sucking insects that infest sugarcane [Saccharum spp. (Poaceae)] around the world, scale insects (Hemiptera: Coccomorpha) stand out with 103 recorded species. Most of them are frequently regarded as secondary or occasional pests (Garcia Morales et al., 2016). In Brazil, eighteen species of scale insects have already been reported on sugarcane. Of these, Aclerda takahashii (Kuwana, 1932) (Aclerdidae), Margarodes sp., (Margarodidae) and Saccharicoccus sacchari (Cockerell, 1895) (Pseudococcidae) are known to the state of Rio Grande do Sul (Garcia Morales et al., 2016; Borges Filho et al., 2019; Monteiro et al., 2019).First online
